Determination of the Rate Equation for a Certain Reaction by a Single Kinetic Pursuit

Abstract

In order to obtain the reaction kinetics and the rate constant for a certain reaction by a single kinetic pursuit, several possible integrated rate equations were included in the program for the determination of the reaction kinetics. The rate constant for each rate equation was calculated by the least-squares method from the values of kt and t. Then, the value of conversion (x, M) at the appropriate time was calculated using the thus obtained rate constant (k). The sum of the squares of deviation between the observed and calculated points at the same time was divided by the square of initial concentration to normalize : S_q=Σ (Δx)²/a². The rate equation to give the minimun value was chosen as the one for this reaction. Several examples were given with some discussions.
